Description

Diisononyl Adipate (CAS NO 33703-08-1) is a high-performance, low-volatility diester plasticizer prized for its excellent permanence and low-temperature flexibility. This versatile chemical is a critical component in formulating durable and flexible polymer compounds, offering superior resistance to extraction and migration compared to many general-purpose plasticizers. It is essential for manufacturers in the plastics, polymer, and specialty chemical industries seeking to enhance product performance and longevity.

Application

• Primary Plasticizer for PVC: Used in calendering, extrusion, and plastisol formulations for products like wire & cable insulation, automotive interiors, and synthetic leather.
• Co-plasticizer for Specialty Polymers: Enhances flexibility and low-temperature performance in nitrile rubber (NBR), polyurethane (PU), and other elastomers.
• Lubricant and Synthetic Base Oil: Serves as a high-quality base fluid for synthetic lubricants and greases requiring thermal stability and low pour points.
• Adhesive and Sealant Formulations: Imparts permanence and flexibility to high-performance adhesives, caulks, and sealants.
• Functional Fluid: Used as a component in hydraulic fluids, heat transfer fluids, and other industrial functional fluids.
• Cosmetic and Personal Care Ingredient: Acts as an emollient and solvent in cosmetic formulations, valued for its low odor and skin feel.
